FINISHING-TOOL FOR WOOD-SHAPING MACHINES.

SPECIFICATION forming part of Letters Patent No. 602,612, dated April19, 1898.

Application filed August '7, 1897.

T0 aZZ whom, it may concern:

Be it known that I, ALEXANDER M. BAGBY, a citizen of the United States,residing at Opelika, in the county of Lee and State of Alabama, haveinvented certain new and useful Improvements in Finishing-Tools forWood- Shaping Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in devices for shaping and dressingor finishing the edges of woodwork and preparing the same for thereception of oil, paint, or varnish.

The object of the invention is to provide a simple, cheap, and efficienttool adapted to take the place of sand-belt machines, sandrolls, &c.,and also to dispense with hand labor, which, on account of the delicateoperation of finishing elaborate scrollwork and the like, is still in alarge measure employed, and thus cheapen the cost of production of thearticle.

A further object is to provide a tool which is adapted for finishingedge surfaces of different configuration and which requires no specialmachine for its mounting, but is adapted to be operatively mounted uponthe rotatable spindle of an ordinary wood-shaping machine or thespindles of machines employed for other purposes.

W'ith these and other objects in view the invention consists in a toolof the class described embodying certain novel constructions, as

will be hereinafter more fully described, and

particularly set forth in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of aportion of a woodshaping machine having my invention applied thereto;Fig. 2, a central vertical section of the same. Fig. 3 is a sideelevational view of the tool on an enlarged scale; Fig. 4, across-sectional view of the same. Figs. 5 and 6 are embodiments of myinvention adapted for beading, rounding, beveling, and other specialwork; and Fig. 7, an enlarged detail perspective view illustrating theform of smoothing and finishing tooth.

Referring now more particularly to the accompanying drawings, 1represents the bed Serial No. 647A64. (N0 model.)

or table of a wood-shaping machine, and 2 the rotatable spindle thereofprojecting through and vertically adjustable in the usual manner in thetable-orifice 3.

My improved dressing or finishing tool comprises a cylindrical body 4,having the longitudinal opening 5, by which it is adapted to be fittedon the spindle. The circumference of said cylinder is provided withdiagonallyarranged rows of teeth 6, extending from one end thereof, butterminating short of the other end, leaving a smooth or toothless face7, the purpose of which will be hereinafter described. The said teeth 6are formed by punching or cutting the metal of Which the cylinder ismade previous to tempering and bending or displacing one of the sideedges of the cut portion upward to form a broad tooth. The tooth thusformed has a broad, slightlyinwardly-curved cutting edge 6, beveled onits under side, and an upwardlycurved or converted body portion 6, andthe edge 6 of the opening at the base of the tooth is beveled, fromwhich point said opening gradually decreases in depth, as illustrated inFig. 7. These teeth in operation do not file or rasp the wood, but havea slight shaving action thereon, and the peculiar construction of theteeth and diagonal disposition of the rows of same effect rapidclearance or insure that the dust or shavings removed from the wood willbe conducted to one side by the centrifugal action of therapidly-rotating tool and gumming or choking of the teeth prevented. V

The construction of tool disclosed in Figs.

1, 2, and 3 is adapted for smoothing or finishing up simply. In Fig. 5 Ihave shown this tooth constructed with parallel circumferential grooves8, forming a central boss 9, of the same diameter as the body of thetool, for operating upon the beads and grooves of intaglio or sunkenbeaded work, while in Fig. 6 the body of the tool is cylindricalthroughout and provided at each end with an integral collar 10, having asmooth outer face 11, constituting the equivalent of the faces 7 of theforms of tool illustrated in Figs. 1 to 5, inclusive, and a curved orbeveled inner side face 12, over which the rows of teeth extend. Thislatter construction of tool is employed for ing up the plane surface ofthe edge.

rounding or beveling off the corners or corner edges of woodwork whilethe toothed body portion of the cylinder is dressing or finish- By thisit will be seen that the different forms of tool herein shown anddescribed are adapted to act upon edge surfaces of different configuration, and thus I do not limit myself to making the body of the tool ofany specific shape or contour.

In use my improved tool is mounted upon the spindle 2 of the wood-shaperand rests upon a collar 2 thereon and is firmly clamped againstindependent movement by a nut 2 a bushing, key, or any other suitablefastening means, or it may be mounted upon the rotating spindle of anyother machine, and said spindle is then rotated at a rapid rate say fromthree thousand to five thousand revolutions per minute. The shaped edgeof the board or piece of woodwork 13 as roughly cut out by the saw isthen brought into contact with the tool and held in contact therewithuntil all irregularities of surface are removed and said edge isperfectly true, finished, or smoothed ready to receive the oil, paint,or varnish. As the tool is made of tempered steel it will operatereadily upon ragged or imperfectly-sawed surfaces, which could not bereduced and finished by a sandbelt machine or sand-roll without frequentrenewal of the surface thereof or by hand work without much labor andloss of time. Under ordinary conditions my improved tool, which can bemanufactured and sold for a small sum, will last a month when inconstant use, and thus it will be seen that by its use the cost offinishing wood articles will be materially reduced and valuable timesaved.

An important feature of my tool lies in its capability of being usedupon any kind of machine having a rotating spindle and in its simplicityand cheapness as compared with sand-belt and sand-roll machines.

The smooth face 7 of the tool enables the employment of a form orpattern 14 with the article being finished. NV hen the edge of saidarticle is reduced and finished in accordance with the contour andconfiguration of the guide edge 14 of the said form 14, the smooth face7 will not injure or reduce the form when coming in contact with saidguide edge.

I am aware that heretofore it has been pro- 3 posed, to employ rotaryfiles for finishing metal, and to such I make no claim, as it is obviousthat my improved wood-finishing tool has no filing or rasping actionwhatever and that such devices could not be employed for the purpose forwhich my invention is intended.

It will thus be seen that I have provided a tool which is simple andcheap in construction and simplifies the operation of dressing orfinishing wood articles, thus lessening the cost of production of thesame.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, is

1. A tool for dressing or finishing edge surfaces of wooden articles,comprising a cylindrical body provided with diagonal rows of teethintegral with the body and projecting outward therefrom, the teeth ineach row being independent but arranged in close relation to each other,substantially as described.

2. A tool for dressing or finishing edge surfaces of wooden articles,having a cylindric body portion formed with a longitudinal opening, andhaving its outer face provided with diagonal rows of teeth, extendingfrom one end and terminating short of the other end thereof so as toleave a smooth-surfaced face, the teeth in each row being independent,but arranged consecutively in close relation to each other,substantially as described.

3. A tool for dressing or finishing wood, comprising a cylindric bodyportion formed with an opening and provided on its periphery withdiagonal rows of teeth, each tooth having a broad cutting edge 6 and anupwardly curved or converted body portion 6 the edge 6 of the opening atthe base of said tooth being beveled and the opening below the cuttingedge gradually increasing in depth from said edge 6, said diagonal rowsof teeth extending from a point adjacent one end of the tool andterminating short of the other end thereof, so as to leave asmooth-surfaced or untoothed face, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER M. BAGBY.
